Equivalent ratio for 12/9
Oliga [24]
In order to make a fraction a ratio, you must simplify it if it is needed. So for 12/9, you can divide 3 from the numerator and denominator. That would equal 4/3. Now that it is simplified, you can make it into a ratio. (can be using ":" or using the word "to") 
One way it can be used is --> 4:3
Another way --> 4 to 3 
Good luck!

-2 1/4 / (-1 1/2) =<br><br> A) 1 1/2<br><br> B) -1 1/2<br><br> C) 3 3/8<br><br> D) -3 3/8
adell [148]

Answer:

A) 1 1/2

Step-by-step explanation:

First, make sure both of the fractions are improper fractions. -2 1/4 will become -9/4 and -1 1/2 becomes -3/2. Then we do the keep, switch, flip trick and get -9/4 X -2/3 and multiply across. Since we have two negatives, the answer becomes positive. When we multiply across we get 18/12, then we reduce and get 1 6/12 which is the same as 1 1/2.

A circle has a radius of 6 in.
yuradex [85]
The circumference of a circle can be calculated using the following equation;
circumference = 2πr
The radius of the given circle = 6 in.
The circumference of the circle = 2π *6
                                                  = 12π in.
circumference of a complete circle is when the central angle is 360°.
we are asked to find the length of an arc when the central angle is 45°.
the length when central angle is 360° = 12π
therefore when central angle is 45°     = 12π /360 * 45
     the length of the arc = 1.5π in.

#5 The MAC is 4 centimeters. Find the circumference of B. Round your answer to the hundredths.
bixtya [17]

Answer:

C ≈ 11.71 cm

Step-by-step explanation:

using the ratio arc  AC : circumference C = angle at centre of sector : 360°

\frac{AC}{C} = \frac{123}{360} , that is

\frac{4}{C} = \frac{123}{360} ( cross- multiply )

123 × C = 4 × 360 = 1440 ( divide both sides by 123 )

C = \frac{1440}{123} ≈ 11.71 cm ( to the nearest hundredth )
